DIVIDED CAR-AXLE.

SPECIFICATION formingpart of Letters Patent No. 329,604, dated November3, 1885,

Application filed April 30, 1885. Serial No. 163,935.

To aZZ whom it may concern.-

Be it known that we, HANS THIELSEN and HENRY WV.DILG,citizens of theUnited States, residing at Portland, in the county of Multnomah andState of Oregon, have invented certain new and useful Improvements inDivided Oar-Axles; and we do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

The object of our invention is to provide a simple and effective meansof connecting the parts of a divided car-axle in such a manner as tofacilitate access for lubricating or replacement of parts, and so thatthe bearings and packing of the loose axle-section in theconnecting-shell can be readily adjusted to diminish or prevent unduewear of the same, as hereinafter set forth.

In the annexed drawings, illustrating the invention, Figure 1 is aperspective View of our improved divided axle. Fig. 2 is a plan view.Fig. 3 is a cross-section through the packing devices. Fig. 4c is alongitudinal section. Fig. 5 is a cross-section through the brasses.Fig. 6 is a perspective view of one of the brasses. Fig. 7 is aperspective view of one of the keys. Fig. 8 is a perspective view of oneof the packing blocks or glands; and Fig. 9 represents a modified mannerof packing by means of a cylindrical flanged gland inserted in the endof the box portion of the connecting-shell. 7

Like letters of reference are used to indicate like parts in the severalviews.

A and B designate, respectively, what we shall term the fixed and looseportions or sections of a divided car-axle, each part of which inpractice will be arranged to rotate in a suitable ljournal-box and havesecured to it one of the car-wheels in the usual manner. To the innerend of the fixed axlesection A is firmly secured the tubular hub orshank portion 0 of a coupling box or shell, D, by which the looseaxle-section B is received. The body of the shell or box D isthree-sided, as shown in Figs. 3 and 5,- and together with its hub orring portion 0 may be cast of steel or other suitable metal. In eachlateral wall of the coupling-box D is an oblong rectangular (N0 in odclopening, a, for the reception of one of the brasses E, that take thewear of the loose axle. These brasses may be made of any suitablematerial, and are each formed with a concaved under surfacecorresponding with the circumference of the adjacent axle. On theirupper surfaces and sides the brasses E are provided with grooves ordepressions b b, that form, in conjunction with the contiguous walls ofthe shell or box D, a series of cups or receptacles for lubricating-oil.Beyond each end of the large oblong opening a is a smaller opening, 0and 0, each of which extends across the box D. The opening c,which isnearest the fixed axle,is for the reception of a key, F, while theopening 0, at the other end of the box, receives a packing block orgland, G. The keys F and packing-blocks G are similarly formed, as shownin Figs. 7 and 8, the block G being of less depth, however, to affordroom between it and the loose axle B for an elastic packingring, d. andalso to provide space for a spring, e, be tween the top of the block Gand the under side of a lid, H, that is attached to the wall of the boxD on each side. The circumference of the loose axle B is preferablyformed, as shown in Fig. 4that is, with reduced portions F, E, and Gforengagement with the keys F, brasses E, and packing-blocks G,respectively, an elastic packing-ring, (I, being placed beneath thelatter, as before remarked. The intervening collars, f f, thereby formedon the axle B, and which are of equal diameter therewith, thus serve asshoulders or bearings for the inner portions of the brasses and keys bywhich the parts of the axle are connected. The lower edges of thebrasses E and keys F are beveled slightly, as shown in Figs. 5, 6, and7, to afford spaces to prevent them from coming in contact with theirfellows, and thus admit ofadjustment inward upon the axle to compensatefor wear of their concave surfaces. The arrangement of the brasses,keys, and packingblocks in three sets within a three-sided box or shellfixed to one portion or half of a divided axle and adapted to engage theloose half of said axle, as described, combines the obvious advantagesof great strength with lightness of structure and facility in theadjustment of the brasses against the loose axle-section in any requireddirection. The lids H may be se cured by means of 'screw-'boltsg'audnuts" h,- or they may be formed on each side with perforated lugs 7c 70, that interlock with similar lugs, m m, on the box D,headed hinge-pins 5 K K being passed throughi'saiddugsandsecured bybow-pins pp, passing through perforations near their ends. That portionof each lid H which is immediately over the-adjacent brass is thickenedto furnish a suitable bearing for a screw-bolt and nut, L, by means 7 ofwhich the pressure of the several "bra's'ses can be regulated. A packingof india-rubber or other suitable material should be placed beneath theedges of the lids before they are I secured. It will beobser'ved thatthe lids H extend over the keys E,brass'e"s E, an'd'packing-blocks G,with their interposed springs, e, and'thus hold said'parts fir'n'i'lyinposition,

In each lid H is an apertureclosed by a screw-pl'ug,M,"for introduc'ing'oil to the space above thebrasses without r'e'moving or ,unfa'stening the lidf-Thelubrica'tihgoilobtains access to the axle 'throu'g'h'the grooves bl), that extend downthe sides ri'fthe brassesf It will be observed that theflo'ose axle B'meets the'fixed axle A in'the tubular o port-ion C of the shell'o'rcoupling-box D,and

By packing the loose axle withinthe box D by means "bfpackingblocks G, set in recesses c with theirlower ends resting on an elastic packingring, d, and having springseabove, between said blocks G and the lid H, we provide a very simple wayof rendering thebox dustproof, and preventing the escape of oil.
